Tonrnno TUBE COMBINED WITH MEMBERS EOR STARTING AND SETTING THE TonPEDoCONTAINED THEREIN. Q

Application filed May 3, 1926, Serial No. 106,559, and in France June25, 1925.

retaining valve and the gyroscope which,

once the torpedo is placed in position in the torpedo tube installed ina submarine or other vessel must be adapted to undergo a change ofposition or a setting from the outside by means of keys or other similardevices engaging through the tube and entering into the torpedo. Thesecontrolling or setting keys must be withdrawn or move out of the wayautomatically when tiring takes place. I

Now, in installations at pres nt in use, the possibility exists offorgetting to open or setthese members. It the air retaining valve hasnot been opened it is quite possible to discharge the torpedo from thetorpedo tube but, as its engine is not supplied, it will stop.Similarly, of the inclination of the axis of the gyroscope has not beenadjusted, or has not received the required setting the torpedo willtravel in a'talse direction.

According to the invention such accidents are rendered impossible onaccount of a conjugation between these starting and setting or adjustingmembers on the one hand and a movable essential member of the torpedotube on the other hand, the conjugation being such that the tube is notready for the launching operation unless the keys have been previouslymoved into the desired position in order to effect the starting andsetting operations. In practice, the essential member of the torpedotube is preferably the breech door, the conjugation with the keys beingsuch that the breech can only be closed when the keys have all beenplaced.

The invention comprises a particular form of construction in. which thekeys are arranged in such a way that their axes can be made not tocoincide exactly with the axes of the catches in which they have toengage V for the purpose of controlling the valve or setting thegyroscope.

Mechanical connecting means with the front door of the tube or any othermember the movement or which is conjugated with that off this door willeffect, according to a known principle. the withdrawal of the keys orother controlling or adjusting members,

while the opening movement of the said door takes place, so that thetorpedo will be free to travel through the tube at the moment ofdischarge.

Finally, in the case when a torpedo is to be removed from its tube forinspection purposes or for any other ,reason, an additional device,conjugated with the'opening movem'ent'ot the dooi of the breech isprovided in order also to produce, according to the invention, thewithdrawal of the keys thus enabling the torpedo to be freely withdrawnthrough the rear opening of the tube without any risk being run ofdamaging the torpedo itself or the said keys. This device operates inthe same way when a torpedo is being placed in the tube.

A practical constructional example of the invention is illustrated inthe accompanying drawings, in which:

Figures 1 to 19 show in full lines the manner 111 whlch one singleoperating or setting key (for example the key i'or adjusting or settingthe gyroscope) is arranged so as to be in operative relationship withthe device ior closing the breech; operative relationsh p at the sametime with other keys being obtained, as shown in Figures 21' and 22,

by'essentially similar means.

The shaft D controlling the longitudinal displacement of the shaft 0 maybe supported at one end by the casing C, at the other end by a suitablebearing a; it receives its movement, for example, through a transmissionarrangement formed by levers and links (F, d, (Z actuated, for example,by a hand lever (Z pivotally mounted upon a pin (Z carried ina hearingal and. adapted to move to either side of the vertical plane passingthrough the axis of the pin about which it turns (Figs. 7 and 9).

The hand lever (Z is connected by means of a pm (Z to a transverse rod Gsupported in twoseats g mounted upon the tube A the said rod serving, aswill be seen hereinafter, as a member for obtaining operativerelationship with an essential movable member of the torpedo tube suchas the breech closing ring A*.

The rod G is provided with two spurs or projections and g.

The spur is adapted to come into engagement with the arm k of a bellcrank lever h -h turning upon a pin k carried upon the tuberfi; thesecond arm k of this lever is adapted to efitect the movement of alocking pin 7L5, guided in a bearing ]L -l11()lll1id upon the tube A bymeans of an oval shaped eye and a projecting end or stud 72,. I

' The arm 7& is extended in a finger 71, turning upon a pin it in theplane of the arm. This. movement of b can only take place in onedirection (from right to left, Fig. 1.2); the plane face of h, byabutting against the bottom of the notch or recess in 72 compels 7&7 tomove in the other direction so as to place itself in alignment with 71without it being-possible for it to pass beyond this position. A specialdevice, described hereinafter, moves 7L back into its normal position atthe proper time, when this member has been displaced.

lVhen a torpedo is placed in the tube, the members provided or formedupon the latter occupy the positions shown in Figure 14; the front doorA is closed, the breech door A is open, and the key 0 has beenautomatically withdrawn as a result of the opening of the door of thebreech.

Under these conditions the transverse rod G is thrown back to the rightof the tube, the arm 71 of the bell crank lever ]L1-]L: is in engagementwith the projecting piece or spur g of G; the front door being closed,the rod 2'" is'pushed backwards; the end of i is not in engagement withg. The stop is is behind the movable finger h; the stop K is behind thelocking member it.

lVhen the torpedo has been placed in position it is impossible tocomplete the closing of the door of the breech by rotating the ring Aunless the key 0 has been moved into position. In fact during themovement of rotation of the screwthreaded ring A for the purpose ofclosing the door, if the key 0 is in a withdrawn position (Fig 14), thestop K Will abut against the locking pin it which will prevent thescrewthreaded ring A from turning through the requisite angle in orderto complete the closing the breech. -The door of the breech not belit) 'During the movement of the screwthreaded ring, the stop the arm h"'mentof rotation, raises upon the lever (Z this movement will havedriven the rod G towards the left ofthe tube (Figjlo). lever -7l/ whichis in engagement with the projection or spur g 'provided'upon G, the mamhas carried backwards the locking memberh thus allowing the stop K? topass.

During this movement the end n makes contact again with the finger I17and brings it back into 'aligmnent with the arm 7&1 by fresh pivotalmovement about Its; the stop 70 will therefore be able toearry along 717during the movement ot'the screwthreaded ring for opening the breech. 7

The door ofthe breech being closed, firing may he proceeded with byadmitting fluid into the press A for this purpose; As a result ,ofthepush exerted bythe piston A; through'the'medium of the link Aan'd thelever Aflthe front door A turns about its hinge pin A2 The piston Acarries along :thelever i which in its turn'carriesalong the arm 2' ofthe lever z' through the The-"arm 2' of this lever, through the mediumof ithe spur of qi orces the. rod G to move ,to'wz'irds the right.

After the torpedo has been launched, during the movement for the closureof the front door, the transverse rod Gr undergoes no action and remainsstationary, the key therefore remains withdrawn.

In the example. shown in Figures 1 to 19 the invention has beenillustrated in its application to the, control and operation of onesingle member such as the key c -0 provided for the purpose of settingor adjusting the gyroscope; but it is obvious that the new device may beemployed for'the control of a varying number of members.

7 For instance the movements for the withdrawal and placing in positionof a series of members may be placed under the control. of one and thesame transverse rod G. In this way the key for operating the airretaining valve maybe connected to the -transverse-rod G in addition tothe gyroscope setting key.

Figures 21 and 22 show the arrangement of the additional members mountedupon the torpedo tube and adapted to be in operative relationship withthe rod G, which members serve for the control of the said second key.In these figures C is'a casing similar to the casing C shown in Figure4,
